Which stage of mitosis is characterized by the reformation of the nuclear membrane?

During telophase, the reformation of the nuclear membrane occurs as chromosomes reach the opposite poles of the cell and begin to unwind back into their chromatin form. This marks the end of the nuclear division process, allowing two separate nuclei to form within the emerging daughter cells. The re-establishment of the nuclear membrane is a critical step, as it sets the stage for the final processes of cell division, leading to cytokinesis. In contrast, other stages such as prophase, metaphase, and anaphase have different functions; for example, prophase involves chromatin condensing into visible chromosomes, metaphase is characterized by the alignment of chromosomes at the cell's equatorial plane, and anaphase involves the separation of sister chromatids toward opposite poles.
